This work discusses a fast generation procedure of authentication codes, for multimedia content cryptography, whose length (and computational complexity) can be tuned accordingly to the specific mobile application and service. In this work, we propose a digital algorithm to generate a pair of long (asymmetric) keys from one short primitive key. According to our results, the devised procedure provides a watermarking algorithm to hide the authentication information inside the multimedia content (intra-frames of MPEG video streams or JPEG images) with the same robustness of similar previous attempts but with less computational complexity.
